Map and Archival Evidence of the Historical Avulsion of the Brahmaputra River

The Geographical Journal, EarlyView.
Short Abstract One of the world's great rivers, the Brahmaputra, avulsed—changed course—significantly sometime between the dates of 1765 and 1830. These are the dates of surveys by James Rennell (grey) and Richard Wilcox (black), both under the direction of the East India Company; no other surveys between these dates can refine the estimate of the ...

Boniteza's Arts Chair, Pedagogical Curatorial Practices with Contemporary Artists as Arts‐Based Educational Research

International Journal of Art &Design Education, EarlyView.
Abstract This article puts forward a new methodology in artistic education. It is based on scientific utopia as it aims for the implementation in schools of the cátedras de la Boniteza (the Boniteza's Art Chair), where an inhabiting artist changes the institution from within through the development of quality art projects.

First occurrences of Trionychidae (Testudines, Cryptodira) from the Miocene of Poland: Detailed cranial anatomy and biogeographic implications

Journal of Anatomy, EarlyView.
Fossil finds from three Middle Miocene sites in Poland reveal the northernmost known presence of trionychid turtles in Europe, tentatively identified as Trionyx cf. vindobonensis, suggesting a warmer climate that supported thermophilic species in Central Europe during this period. Abstract Modern trionychids (Testudines, Cryptodira) have a pan‐tropical

Remarks on the type locality and current status of the foraminiferal species Rzehakina epigona (Rzehak, 1895) [PDF]

, 2001
A likely topotype locality is proposed for Rzehakina epigona. As the type specimen of Silicina epigona Rzehak, 1895 is assumed to be lost, we undertook a search for new material in the type area, Zdounky village in Moravia. A single locality provided a

Microbially generated ferruginous crusts: A potential biosignature of continental input in coastal settings

Sedimentology, EarlyView.
ABSTRACT Thin ferruginous sandy crusts are common on top of sandstone beds in the Early Permian post‐glacial deposits of the Paraná Basin in southern Brazil. These crusts usually preserve wrinkle structures, suggesting that they might be a product of microbial mediation.

Hydraulic fracture initiation and propagation mechanisms in deep coalbed methane reservoirs based on Computed Tomography image reconstruction

Results in Engineering
China has great potential for deep coalbed methane (CBM) resources. Nevertheless, due to the ''three high'' geological conditions, traditional fracturing techniques for shallow reservoirs face adaptability bottlenecks.
